DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. The external storage device 11 is a magnetic disk device. In addition to the document data, the external storage device 11 stores document data such as format data, document management data such as a document name, and keyword management data. Here, the document management data and the keyword management data in the external storage device 11 are read out under the control of the read / write circuit 12 and preset in the corresponding document management memory 13 and keyword management memory 14.
Further, the document data in the external storage device 11 and the corresponding format data are read out under the control of the read / write circuit 12 and preset in the corresponding document memory 15 and format memory 16.

The keyword detecting device 17 is a key input device 1
The document management memory 13 and the keyword management memory 14 are referred to on the basis of the keyword inputted from 8, and the document name of the document including the keyword is given to the reading / writing circuit 12.

The document display circuit 19 causes the CRT display device 21 to display and output the document data in the document memory 15 based on the setting format in the display memory 20 via the display memory 20.

FIG. 3 is a diagram for explaining the keyword management data. The keyword management data is composed of keywords and document management numbers corresponding to the keywords. Here, the keyword is an arbitrary character or character string in the document data displayed on the text screen of the CRT display device 21 is designated as a keyword for document search. The document management number is a series number that is updated each time a new document is created, and one or more document management numbers can be set in correspondence with the keyword.

FIG. 4 is a diagram for explaining the document management data. The document management data is composed of a document management number and a document name corresponding to it. According to this document name, the document data (text data) and its format are shown. Data and are specified.

Next, the operation of this embodiment will be described. Now
In addition to the document data, format data, document management data, and keyword management data are registered in the external storage device 11 for each document. In this state, the read / write circuit 12 reads the document management data and the keyword management data from the external storage device 11 and presets them in the corresponding document management memory 13 and keyword management memory 14.

Here, when searching for desired document data from the external storage device 11 and displaying and outputting it, a keyword is input from the key input device 18. FIG. 5 is a flowchart showing the document search operation when a keyword is input. First, when a keyword is input from the key input device 18 (step S1), the keyword detection device 17 determines the keyword management memory 1 based on the input keyword.
4 is searched (step S2), and the keyword management memory 1
It is checked whether or not the corresponding keyword exists in 4 (step S3). Here, if the corresponding keyword is not preset in the keyword management memory 14, the process returns to step S1 to invalidate the entered keyword, and the keyword can be input again.
If the relevant keyword is preset in the keyword management memory 14, the document management number corresponding to the keyword is read from the keyword management memory 14 (step S4). Next, it is checked whether or not a plurality of document management numbers have been read from the keyword management memory 14 (step S5). Here, when only one document management No. is set in the keyword management memory 14 corresponding to the relevant keyword, the process proceeds to step S11, and the keyword detection device 17 causes the keyword management memory 1 to operate.
The document name corresponding to the document management No. read from No. 4 is retrieved from the document management memory 13, and this document name is given to the reading / writing circuit 12. Then, the read / write circuit 12 reads the document data corresponding to this document name and its format data from the external storage device 11, and the corresponding document memory 1
5. Set in format memory 16. Then, the document display circuit 19 converts the document data in the document memory 15 into the format memory 1
Based on the setting format in 6, the CRT display device 21 displays and outputs (step S10).

On the other hand, if a plurality of document management Nos. Are set in the keyword management memory 14 corresponding to the relevant keyword, the process proceeds to step S6, where the keyword detection device 17 reads the plurality of document management Nos. The document names corresponding to the document management numbers are sequentially searched from the document management memory 13, and the document names are read from the document management memory 13. Then, a list of the document names read from the document management memory 13 is displayed on the CRT display device 21 (step S7). Here, when the document name of the search target is selected and instructed from the key input device 18 from the list display screen (step S8), the read / write circuit 12 reads the document data corresponding to the document name from the external storage device 11 (step S9). ), And display output from the CRT display device 21 (step S10).

As described above, in this embodiment, desired document data can be searched and displayed by inputting a keyword.

Although the keyword management information is stored in the external storage device 11 in the above embodiment, the keyword management information may not be stored. Here, in the above-described embodiment, the entire document data is the keyword target that can be specified for document retrieval, but only a part of the document data, for example, the range of the first few lines is the keyword target, and the input keyword By searching for whether or not is included in a part of each document data, it is not necessary to store the keyword management information in the external storage device 11.

Further, in the above embodiment, the keywords are input from the key input device 18, but the keywords set in advance are displayed together with the document name in a list, and a pointing device such as a mouse is used to display them on the screen. By designating a desired keyword with, the operability is improved and the document search can be efficiently performed.

Further, if the document search is performed according to the logical product condition or logical sum condition of a plurality of keywords, the search can be easily performed even if the number of documents increases.
